Product Description
Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.
Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest.
The earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which British chemist and inventor Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from the journal Philosophical Transactions of the Royal Society of London: "Had I been so fortunate as to have obtained more certain evidences on this subject, and to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium."

- It depends on how tight, very tight, aluminum will be together, that will certainly not water
- Q:How much is the 25mm aluminum coil at current market?
- You must mean 25-wide aluminum coil. The price consists of the aluminum ingot price and processing charges. For example, if the processing price is 4500 yuan, it is relatively cheap. 25mm-wide aluminum coil is very narrow, so it will be much complicated to strip.
- Q:Can aluminum coils be painted for custom designs?
- Yes, aluminum coils can be painted for custom designs. Aluminum is a versatile material that can be coated with various paints and finishes, allowing for a wide range of custom design options.
- Q:What are the different coil slitting methods used for aluminum coils?
- Aluminum coils can be slit using various methods, each offering distinct advantages and applications. Here are a few commonly used techniques: 1. Rotary Shear Slitting: Employing rotating circular knives, this method achieves precise and speedy cutting of aluminum coils into narrower strips. It is ideal for high-volume production of consistently sized narrow strips. 2. Loop Slitting: This method involves passing the aluminum coil through a loop, where rotating knives make the cuts. Loop slitting enables fast processing while minimizing the risk of surface damage, making it suitable for thinner gauge coils. 3. Double Knife Slitting: Using two blades, this technique makes parallel cuts along the length of the aluminum coil. It is best suited for thicker gauge coils and can produce wider strips compared to other methods. 4. Scissors Slitting: This versatile method deploys a pair of scissors-like blades to cut the aluminum coil into strips. It can handle a wide range of coil thicknesses and is commonly used in smaller scale operations or when precise width tolerances are not critical. 5. Crush Slitting: Here, the aluminum coil is pressed against a hardened roller or blade, causing it to deform and rupture along the desired cutting line. Crush slitting is ideal for delicate materials or when minimal burr formation is desired. Each slitting method has its own advantages and limitations, and the choice depends on factors such as coil thickness, desired strip width, production volume, and surface quality requirements. Selecting the appropriate method is crucial for efficient and accurate slitting of aluminum coils.

This creates a thick protective layer on the surface of the coil, making it highly resistant to weathering, scratches, and fading. Anodized finishes are available in different colors and can be customized to meet specific design requirements. 3. To achieve specific colors, textures, and levels of durability, aluminum coils can be painted with various types of coatings. These coatings are applied using a coil coating process, ensuring even distribution and curing onto the surface of the aluminum. Painted finishes offer excellent color retention and weather resistance, and can be tailored to suit individual project needs. 4. For a textured appearance, the surface of the aluminum coil can be mechanically brushed using abrasive materials. This creates a brushed finish, which not only provides a unique aesthetic appeal but also helps hide scratches and blemishes. Brushed finishes are commonly used in architectural applications like interior design, signage, and furniture. 5. Embossing involves imprinting patterns or designs onto the surface of the aluminum coil, resulting in an embossed finish. This adds texture and visual interest to the material, making it suitable for decorative purposes. Embossed finishes can mimic various textures, such as wood grain or stucco, and are widely used in building facades, roofing, and signage. 6. Laminating involves bonding a layer of protective film or sheet onto the surface of the aluminum coil. This laminated finish provides additional protection against scratches, stains, and UV rays. It is commonly used in applications that require high durability, such as transportation, appliances, and electronic enclosures. Ultimately, the choice of finish for aluminum coils depends on specific project requirements, including aesthetics, durability, and environmental factors.
